摘要: 该文对K分布杂波模型统计特性做了深入分析和推导，提出了一种新的运用样本算数平均和几何平均的高精度低运算量的K分布杂波模型参数估计快速算法，并对算法的估计精度作了理论评价。最后进行了计算机仿真实验，实验结论证实了文中所提出算法的有效性与准确性。Abstract: This paper analyzes the statistical characteristics of radar clutter, discusses the K-distributed random process used for describing the amplitude characteristics of the clutter, deduces the formulas of relation between K-distributed and Gamma-distributed random variables, and presents a novel method for estimating parameters of K-distributed clutter. Finally, the simulation experimental results of generating the clutter samples and estimating the parameters prove the conclusion proposed.
